title: Influence of rutin on biochemical alterations in hyperammonemia in rats.
abstract: Flavonoids are non-nutritive dietary components that are widely distributed in plants. The present study was undertaken to examine the protective influence of rutin, a polyphenolic flavonoid, on oxidative stress during ammonium chloride (AC)-induced hyperammonemia by measuring the levels of oxidative damage as well as antioxidant status. The levels of tissue (liver, brain and kidney) lipid peroxides and the antioxidants (total thiols, catalase, reduced glutathione and glutathione peroxidase) were analyzed. Hyperammonemia was induced by daily intraperitoneal injections of AC at a dose of 100 mg/kg body weight for 8 weeks. Decreased levels of tissue lipid peroxidation accompanied with increased antioxidant levels in hyperammonemic rats were observed during oral administration of rutin (50 mg/kg body weight), which clearly shows the antioxidant property of rutin. The study of induction of the antioxidant status is considered to be a reliable marker for evaluating the antiperoxidative effect of the polyphenolic compound. Our present findings show the protective role of rutin against lipid peroxidation and suggest that rutin possesses antioxidant potential that may be used for therapeutic purposes.
